Installing the CIT-40








If Pulse dialing is required refer to the section on Setting Dialing Mode.
Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
Choose a wall location that is free of obstructions and permits space for
cable or conduit runs.
Ensure mounting can support 4lbs (1.8kg) and any additional load to which
the telephone may be subjected.
Ensure that none of the electrical connection circuits are live.
Bring Tip, Ring and Ground wiring to the location where the wiring access
opening in the back of the CIT-40 will be when the telephone is installed.
Remove the eight (8) cover screws from the front of the unit and carefully
remove the front cover assembly. NOTE that the handset and all
electronics are attached to the front plate. The front cover may be
separated from the back box by disconnecting the harness plug.

Use the enclosure as a template to locate and drill holes for #8 or M4
mounting screws or other suitable attachments.
Feed Tip, Ring and Ground wiring through the wiring access opening and
secure the unit to the wall.
Attach individual wires from the exchange (Tip/Ring/Ground) to the terminal
strip (Tip & Ring are not polarity sensitive), or plug the RJ11 connector into
the socket if this termination method was chosen. Even if an RJ11
connector is used an approved earth ground must still be provided to the
ground connection on the terminal strip.

Ensure all connections are tight, then replace and secure the cover.


Connect the telephone into the system.
Test the unit by calling to and from another unit on the exchange.

See: Setting Dialing
Mode
See: Figure 2 Dimensions
Tip: The CIT-40 may be
wired directly to the
terminal block or an
RJ11 connector may be
used.
Tip: Use the driver bit
provided to remove the
tamper resistant screws.
See: Figure 3 Mounting.
See: Figure 4 - Electrical
Connections
Note: an approved earth
ground must be
connected to the ground
position on the terminal
strip regardless of Tip
and Ring wiring method.
Operation

Once the Model CIT-40 Telephone has been properly installed and
energized operation is identical to most other single line telephones.
Field Repairs
Note: The only field repair permitted is the replacement of fuses and changing
the Tone/Pulse setting. All other repairs or alterations must be carried out by
Guardian Telecom or an Authorized Service Depot. See Warranty and
Disclaimer for details.

Setting Dialing Mode
The CIT-40 is shipped from the factory set for DTMF (Tone) dialing mode. If
loop disconnect (Pulse) dialing is required proceed as follows.




See: Figure 4 Electrical Connections
Carefully remove the front cover assembly and separate from the housing by
disconnecting the harness plug. NOTE that the handset and all electronics
are attached to the front plate.
Move the jumper from pins 1 & 2 to pins 2 & 3.
The set will now be in pulse dialing mode, it can be returned to tone mode
by moving the jumper back to pins 1 & 2.
Carefully replace the front plate and install all eight screws. Do not over
tighten the cover screws; there is a flexible gasket between the cover and
the body. Excessive tightening of the screws deforms the gasket and
reduces the weather resistance of the set.
Fuse Replacement




Disconnect the telephone from Tip and Ring power supplied by the PABX or
central office before attempting to replace the fuse.
Carefully remove the front cover assembly and separate from the housing
by disconnecting the harness plugs. NOTE that the handset and all
electronics are attached to the front plate.
Replace fuse in fuse holder.
Carefully replace the front plate and install all eight screws. Do not over
tighten the cover screws; there is a flexible gasket between the cover and
the body. Excessive tightening of the screws deforms the gasket and
reduces the weather resistance of the set.
WARNING!


Replace only with a 0.25 amp 3AG fast blow fuse. Failure to do so will void
the warranty.
If, on reconnecting power, the fuse fails, check the telephone system wiring.
The fuse protects the Tip and Ring line from the telephone system. It is
usually powered at 48 volts DC and must not be connected to 120 volts AC.

Guardian Product Return
Guardian products have been quality tested and are in full working order when shipped from
the factory, given the rugged nature of these products shipping is not expected to damage a
unit. In the unlikely event of a malfunction, Guardian follows the three step procedure below.
Step I - On-Site Correction

The most common source of difficulties with a new product is improper installation in one of
two ways: incorrect wiring connections or connection to an incorrect power source.

Product wiring needs to be properly connected to the on-site wiring. Correct wiring
instructions are shown in the user manual included with the product.

Connecting a telephone to a standard power source, rather than tip & ring, will blow the
telephone’s internal, user-replaceable fuse. In the event of fuse burn-out, disconnect the
telephone from the power source, replace the fuse, and reconnect following the wiring
diagrams provided with the product.
Step II - Return Materials Authorization (RMA)

When a product has been installed following user manual instructions, and the unit fails to
operate, the user must contact Guardian Telecom to obtain authorization to return the
product. This can be done by completing a RMA form online at
www.guardiantelecom.com, or by calling the service telephone number given in this
manual.

After providing information on the product, the owner and the nature of the problem,
Guardian will issue a RMA number, to be shown on documentation returned with the
product.

In addition to the RMA number, shipping documents should include name, address and
telephone number of the owner along with contact information for the person responsible
for the repair and/or the user who identified the malfunction.

(Where a product is being returned for repair from outside of Canada, customs
documentation must show the product’s serial number, date of export [date of purchase],
and a notation that the equipment is: “Canadian goods returning.”)
Step III - Factory Authorized Service

Once received, each product is carefully inspected and tested. If the product is under
warranty, repairs are completed and the product returned to the owner, generally within
five working days of receipt by the factory.

A product that has been subjected to misuse, neglect or accident or is beyond the warranty
period will be evaluated. The service department will provide the owner’s representative
with a repair cost estimate. Once approved, repairs are completed and the product
returned, generally within five working days.
